SAP PowerDesigner (formerly from Sybase) is an enterprise data architecture modeling tool, used to Build a blueprint of the current enterprise architecture and visualize the impact of change before it happens.
The Paradigm geologic and petrophysical interpretation software suite offers a complete package for integrated projects where a team starts from offset well data and leads all the way to mapping of horizons, properties and reservoir models. Geolog, the petrophysical module, is very powerful and versatile. Although they offer separate add-ons, for smaller projects where the petrophysical interpretation is done by a third-party, even the minimum package might be overkill.
SAP PowerDesigner allows our team of data modelers to work and collaborate from a single repository and single data dictionary. This helps enforce consistency as data elements are referenced in other objects. Prior to our use of PD, we might have an element named "ppt" in one table, "participant" in another table and "part" in a third table. By forcing everything to be used from the data dictionary, we avoid these situations because everyone has to go to the dictionary. And we are able to easily do peer reviews on models before they are released because we are collaborating through the use of the repository.
Geolog is extremely robust and powerful in handling large volumes of logs per well and a large number of wells, which is an asset for basin-scale projects.
Geolog is very flexible in terms of customizing log layout presentations and calculating anything via mathematical or logical expressions.
Epos display of fluid production data is very useful in cross-analyzing maturity and organic content versus hydrocarbons produced.
Geolog could use a LAS batch loading graphical interface that doesn't require the use of prompt commands.
Geolog's geologic intervals display has improved in the last versions, but it's still cumbersome to set up and maintain (i.e. adding new intervals, changing stratigraphy).
SKUA-Paradigm should support geographic coordinates in order to avoid the workaround of creating pseudo-coordinates across UTM zone boundaries.
We did have to reach out to support to learn how to properly utilize the repository feature and share the data model across many developers. Support was able to help us get this set up correctly. The downside was it took us several weeks before we gave up and contacted support. We should have done that earlier. I would say, however, the documentation wasn't clear on how to do this. So support was a great big help!
Regarding the petrophysical modules, I have used other petrophysical software packages, and Paradigm is superior in data handling, visualization, flexibility, and batch calculations. Regarding the mapping and modeling, Paradigm is on par with other software I used on the same scale. SKUA-Gocad has some advantages over its main competitor, in terms of data manipulation, but the inability to handle geographic coordinates has a negative impact on my work efficiency.
Oracle SQL Developer Data Modeler : Unfortunately this tool only supports Oracle Databases as a target database, but has many features similar to SAP Sybase PowerDesigner. erwin Data Modeler: Has some issues when switching from Conceptual Model to Physical Model, Impact Analysis, and formatting copy and pasting. Vertabelo: Only supports online models and from a governance perspective, it is impossible for me to connect my target database with an online application because of company policy and regulation requirements.
Paradigm Geolog has allowed us to handle the vast quantities of well log data in order to achieve our research goals and deliver the results to the sponsoring companies.
Paradigm Epos and SKUA-GOCAD have made possible to map the results of our petrophysical analysis on a basin-wide scale encompassing two provinces, without which our research deliverables would not have been possible.
